Abstract

The invention relates to an automobile air conditioner (10) comprising an inside and outside air switching unit (16). The inside and outside air switching unit (16) is provided with a housing (42) accommodating a filter (46). A filter insertion opening (54) forms in the lower side of the housing (42), and the filter (46) can be inserted into the filter insertion opening (54) from the outside. Furthermore, a protrusion is arranged nearby the opening of the filter insertion opening (54). The low end of the filler is prevented from falling out through locked connection between the lower end of the filter (46) and the protrusion (56).

Description

technical field

[0001] The present invention relates to a vehicle air conditioner installed in a vehicle for adjusting the temperature inside the vehicle compartment by blowing air into the vehicle compartment, wherein the temperature of the air is adjusted by a heat exchanger. Background technique

[0002] Heretofore, the car air conditioner installed in the vehicle sucks the inside and outside air into the air conditioner casing provided with the air flow passage therein through the blower fan, and cools the air and cools the air with an appropriate mixing ratio in the air conditioner casing. After the heated air is mixed, the mixed air is blown into the compartment through multiple outlets provided in the casing through the blowing duct, thereby adjusting the temperature and humidity inside the compartment, wherein the cooling air is passed through the evaporative The cooling device is used for cooling, and the heated air is heated by a heating bellows type heating device...
